Hi Guys, I've bought a new workstation pc, i used 3ds max 2013 with vray 64 bit (planing to upgrade to 2015 ) to do my renderings. I was wondering why is my rendering so slow. My modelling isn't that complex and it's not full of ray tracing things like chrome and i'm still a student and part time designer. Mostly it's slow on pre pass 1,2,3 and 4. I do final renders with Medium in irradience map, noise threshold in 0.001 and 1080p resoulution but it takes around 4 - 5 hours. :ouch:

My specs
Cpu - Intel Xeon E5-2680 V2 @ 2.8 Ghz, LGA 2011 with 10 cores and 20 threads
Mobo - P9X79 e Ws
Graphics Card - Nvidia Quadro K4000
Ram - Kingston KVR-16E11/8G DIMM. 32GB in total
SSD - Samsung 840 pro 256 GB x 2
HDD - WD Cavair Black 2tb

Any hardware, suggestions, settings or methods to make my renderings faster? Maybe like overclocking?:p I'm a bit disappointed with this built :( or is it that is normal to take around 4-5 hours??:??:

Any suggestions? I'll appreciate any answer guys :):wahoo::ange: sorry for my english, i'm malaysian :D

I look forward to seeing the responses on this thread. You are someone who actually has a true Intel BEAST server processor. Most people in these forums just regurgitate what they read online. So I am looking forward to seeing the responses! :)

I myself have no experience with the programs you are running, or the CPU for that matter.

What are you using for a reference against the render times? What render engine? What materials do you use? Light setups? Reflections/refractions and number of samples in all those categories? Are they created natively in 3DS or are they brought over from another autodesk product? I've experienced large differences in different years of 3ds as far as render times go, up to a ~25% increase/decrease in render time even.

When your render is working, are you seeing full 100% load on all cores and threads? I've even had problems in 3DS 2011 that would result in the render running at maybe 40% load on all cores.

There won't be much you can do hardware-wise on your system to speed things up, the Xeons are locked these days, no more bus overclocking etc. If you can provide more details on the software/settings side, I can make some recommendations possibly.

It's funny how you presented a specific problem with your specific hardware and software that shows you at least own the tech you speak of. However, you have not gotten many responses. :(

If you had posed the question like, "which CPU is better for these tasks, Intel Xeon or AMD FX", then there would have been about a dozen "CPU experts" giving their two cents about which CPU is better for the software and tasks you are running.

Goes to show you that it is easy to be a expert when to prove your knowledge does not require actual hands on experience with the tech.

You most likely will not get good answers here. You may need to install the software on a friend's rig and benchmark to determine what your speeds should be around. If their rig freezes or takes a day or two, then your rig is light years ahead. LOL

Good luck ;)

You need to realize that render speeds can be greatly affected by changing even a single setting when rendering. You can take a single material in a scene with many materials, change a reflection or refraction sample number etc and increase your render times many many times over. Yes, there are a lot of people who focus mainly on the hardware here but the question, although specific on hardware, was very sketchy on the important details.

That machine listed is a dynamite rendering machine and should chew through anything that is optimized correctly on properly functioning software. The specifics of the scene assets and render engine settings will help get a detailed response.

Yes, as the man above said, the render setting is matter.
Seeing a powerful beast like your rig run extremely slow like that is very frustrating.
My workstation is dual xeon x5650 12 core 24 thread with gtx 670, a decent one / of course it's is much cheaper than your beast. Would you send me your file then I can do a test render on my rig, for analysis ?

Hi!
We have exactly same promblem. Our Dell T7610 2x E5-2680V2 with 65GB RAM are about 2 times slower than our dual X5670 rigs. We have seen this problem at least on some Vray scenes with PhoenixFD sims. Very frustrating!
